tenor

Male voice types and their approximate
ranges.

Tenor is the highest non-falsetto adult male
voice type. Lower than tenor is baritone;
higher is countertenor but this is
largely produced in falsetto. The tenor range extends approximately from
the C below middle C (C3) to the C above middle C (C4), which is also known
as tenor C. Tenors, like sopranos (their female equivalent), are divided into different types: lyric, spinto,
dramatic, and Heldentenor (heroic).

The tenor clef (a C clef on the fourth line
of the stave) is now little used, the music being now usually written an octave above its real pitch, on the treble
clef. In early church music the tenor part was the melody.
